Today I was playing on gorge, holding down a sentry nest. An ubered demoman jumped into the open and started setting up a trap on my nest. Whipped out my trusty SS and the trap disappeared and the uber ended. BOOM! The weapon is useful, but only for turtle engis.

I might start using it also, but if Valve could change the metal cost to "insert number here" in order to have 5-6 shots, and having 0 metal at the end of those shots I would use it all the time, I hate ending all my shots and having some metal left

Version 2
If a projectile is destroyed the 35 metal is refunded but does not give more.

Version 3
(Bizarre idea) If 5 projectiles are zapped and absorbed the short circuit can be "short circuited" into a critical shot. It deals 150 damage and takes a full second to charge, while charging it makes a very loud noise. It also absorbs 100 metal in the shot.

Personally I prefer the first version simply because it prevents uber spamming against soldiers but can reward extra metal when using it on a demo man.

I say let's see how it is now, it was pretty good before for defense, and being able to clear through your buildings should give a lot more bang for your "buck". I think reducing the metal cost too much or allowing a refund would be too powerful, as a turtling engie would be super difficult to take out.
